There are a number of issues that can affect the quality of edge banding machines during production, most of which are related to the unique purpose and design of the machines themselves. When considering the purpose and design of an edge banding machine, it is important to remember that it must serve multiple purposes, including the protection of the workpiece’s edges, the sealing of those edges, and the reduction of deformation. For a finished product to have a flawless edge, the machine must guarantee that the edge banding strips are firmly bonded to the board’s edge and are level and smooth. Additionally, the union between the edge-sealed surface and the other sides must be unbroken, natural, and quick.
- Technical Difficulties with the Equipment
Edge banding strips won’t be a great fit since the engine and track of the machine don’t work well together. Gluing pressure rod that does not work well with the conveyor chain pad might lead to a lack of glue or an uneven coating. Not only does it take more time and effort to trim and chamfer if the equipment isn’t properly calibrated, but the results are also less reliable.
In a nutshell, the quality issues will persist due to the subpar commissioning, repairs, and maintenance of equipment. How sharp or dull your cutting tools are has a direct impact on how well you finish and trim your work. Trimming equipment typically provides an angle between 0 and 30 degrees, with 20 degrees being the most commonly used in mass manufacturing. When using a cutting instrument with a dull blade, the finished product suffers.
- The Workpiece Component
It is possible that the thickness deviation and flatness of a workpiece created from synthetic wood will not be up to par. It’s because of this that adjusting the height of the conveyor’s pressure roller wheels can be tricky. Too little separation between the strips and the workpiece will lead to damage from stress and possible separation. If it’s too far, the plate won’t get squeezed, and the strips won’t be able to band tightly against the edge.
- Edge Banding Strips
Edge banding strips are often composed of PVC, which is very susceptible to environmental factors. Glue’s ability to adhere to PVC strips is diminished by winter’s increased hardness. Over time, surfaces age and lose their stickiness, making glue less effective. Uneven cutting, insufficient bonding strength, and poor trimming performance are the results of paper produced strips’ high toughness and low thickness (such as 0.3mm). Large amounts of edge banding strips being wasted and a high rework rate are therefore major issues.
The pressure rod for strips should be set at a high pressure when using thick edge banding strips. Over-tightening is the most typical mistake. The vertical force on edge banding strips is due to the fact that the strips are somewhat longer than the workpiece. The bonding strength is insufficient and the end of the workpiece is easily lost since the glue has not yet fully set.
